s6, detecting the water content of the dried powder by the moisture detector 15, and collecting the dried powder into the powder collecting barrel 17 for the next step.
In the above step S1, an operator starts the temperature and humidity detector 119 to detect the humidity inside the powder storage tank 116, and when the ideal humidity of the powder is set to S, the powder is in an optimal state for pulverization and is not easy to agglomerate, and at this time, starts the vibration motor 117 to control the powder storage tank 116 to vibrate, so that the powder inside the powder storage tank 116 is vibrated and crushed, and the powder is pumped into the feed pipe 111 by the powder delivery pump 115;
therefore, when the temperature and humidity detector 119 detects that the humidity of the powder in the powder storage box 116 is higher than S, the powder is too high in humidity and easy to agglomerate in the transportation process, the humidity of the powder needs to be reduced, the heating pipe 118 is started to heat and dehumidify the interior of the powder storage box 116, when the humidity in the powder reaches the ideal humidity S, the powder is subjected to vibration crushing and conveying, the power of the powder conveying pump 115 is set to be the rated power, and the powder anti-caking tester 114 is started to detect the powder anti-caking property in the feeding pipe 111;
